XMT-JK808 series intellective temperature adjustment instrument

XMT-JK808 series intelligent （Temperature controller）temperature control instrument is a new meter to meet the market needs. The meter is controlled by single chip microcomputer, every channel setting value and some parameters can be set up independently. It has the advantages of small volume, low power consumption, simple operation, easy control, stable operation, reliable, economical characteristics. It is widely used in the temperature automatic control systems of machinery、chemical、ceramics、light industrial、metallurgy、petrifaction and heat treatment, and so on.

四、Internal parameters：

 Ⅴ、Instrument operation：

5.1、The first menu setting ( public menu setting )：

Press the function key ( SET / I key) 3 seconds, enter into the first channel to the fourth channel the  first menu setting state, this time ’ the first channel display window ‘ and ‘ the second channel display window ‘ respectively display the first menu parameter symbols and parameter values, this time you can press respectively correspond to the ◄（shift）、▲、▼ keys to change the parameter value, after the completion modified, press SET / I key to preserve and enter into the next parameter; modify the other parameters by the same method. If in the setting without any operation 10 seconds, the meter will automatically save and exit the modified state.

 Press the function key ( SET / II key) 3 seconds, enter into the fifth channel and the eighth channel the first menu setting state, this time ’ the fifth channel display window ‘ and ‘ the sixth channel display window ‘ respectively display the first menu parameter symbols and parameter values, modification method is as above.

5.2、The second menu setting ( each channel corresponding to the menu setting )：

 The first channel to the fourth channel parameters respectively press CH1～CH4 three seconds to enter into the corresponding channel menu item, this time ’the first channel display window ‘ and ‘the second channel display window ‘ respectively display the corresponding channel the second menu parameter symbols and parameter values, this time you can press respectively correspond to the ◄（shift）、▲、▼ keys to change the parameter value, modification method is as above “5.1、The first menu setting”.

The fifth channel to the eighth parameters respectively press CH5～CH8 three seconds to enter into the corresponding channel menu item, this time ’the fifth channel display window’ and ‘the sixth channel display window’ respectively display the corresponding channel the second menu parameter symbols and parameter values, this time you can press respectively correspond to the ◄（shift）、▲、▼ keys to change the parameter value, modification method is as above “5.1、The first menu setting”.

Ⅵ、Setting itself：

The meter use in the first time or the surroundings have changer, finding it control not good,  this time you need use the setting itself. For example:

At first set up the corresponding channel setting value, and then enter into the corresponding channel menu, set the corresponding Hy is 0.5～1℃, set the AT=1, “AT” and the measured temperature value flash alternately, the meter enter into setting itself, the meter have three times vibrate, automatic preserved P, I, D parameter and the setting itself finish.

Note：①when the power off during setting itself, as the meter has the memory, it will restart setting itself next time.

②when it need artificially exit during setting itself, set the corresponding channel self-tuning

the parameter AT to 0 so that can exit，but the setting result will not be valid.

Ⅶ、Connection scheme(consult)：

Note：1)The above diagram is an example of XMT-JK818, only for reference, controller’s specific connection should be confirm to the case’s connection.

2)The meter’s signal input used to isolate type Sensor, or that may affect the meter’s measurement.

Ⅷ、Fault Analysis and Clearance:

XMT-JK808 series adopt advanced production process, and have the strict test before leaving factory, it improve the reliability of the meter .The usual fault caused by the wrong operation or parameter setting. If you find the fault couldn’t be cope with, please record it, and contact with the agent or us. Sheet 8-1 is the usual fault of XMT-JK808 series in the daily application：
